RI, when we qualify for a ccw, it is the caliber in which you qualified with, that you can carry. which is why many qualify with (say) a .45 (can be a Colt .45 or 45 ACP), that way that person can carry any caliber, "up to" that .45.
if one were to have (say) qualified with a .38, but carried a 45, or 357? that person would face charges (of whatever the DA pushes)
so here, best to qualify with the biggest caliber. i actually gave thought and had access to a 50AE Desert Eagle, but man, the kick on that and these older hands, wasn't gonna happen. besides, all i carry currently, is a 9MM Hellcat. then too, even with a 15 rnd mag, and one in the chamber, this Hellcat has "heft" to it.
